I went for the first time yesterday! First run was 56.7 secs and my last was 50.6!! It was a big circuit as we used the police training pad
Took a drivers course from a local club. Had so much fun with really helpful instructors hence shaving 6 seconds off my time!
One of my main problems yesterday was I was focusing on the cones directly in front of me rather than looking ahead for the exit and/or next entrance cone. I think you were doing it right but hard to tell from the video. Seems like the cones could have been laid out better on your circuit...i was surprised there wasnt a slalom portion.
